Advanced search with wildcards and operators
In the current version of arsnova.cards, it is difficult to find a card within a cardset or repetitorium using the search function. Also, it is not possible to search with wildcards or operators.
It would be helpful if you could enable an advanced search that allows you to search for terms within a cardset (or repetitorium). The advanced search could be attached to the search bar with a checkbox. To deepen the search, wildcards and operators could be integrated into the search function (for example, as with Open Semantic Search).
For example, you want to search for the description of a cardset. This is unfortunately not possible, because only the name of the cardset theme is searched. (see both screenshots, the cardset "WBS: HTTP" cannot be found via the description "Hypertext Transfer Protocol")
